Direction: The following graph shows the production of wheat flour (in 1000 tonnes) by three companies X, Y and Z over the years. Study the graph and answer the questions.
-
The average production for five years was maximum for which company (s)?
-
- X and Z both
- Y
- Z
- X and Y both
Correct Option: A
From the given bar diagram , we see
Total production of Company X = 300 + 450 + 250 + 500 + 400 = 1900
Number of years = 5
| Average production of Company X = | Number of years |
| Average production of Company X = | = 380 thousand tonnes | 5 |
Total production of Company Y = 250 + 350 + 350 + 400 + 500 = 1850
Number of years = 5
| Average production of Company Y = | Number of years |
| Average production of Company Y = | = 370 thousand tonnes | 5 |
Total production of Company Z = 350 + 400 + 450 + 350 + 350 = 1900
Number of years = 5
| Average production of Company Z = | Number of years |
| Average production of Company Z = | = 380 thousand tonnes | 5 |
∴ X & Z has maximum production
